Turn on Word Verification

Just a word of WARNING.....turn on your word verification under settings/comments. How do I know this? Well lets just say you could be getting some interesting comments that are created by online advertising type robots that go into your comments and make random comments that direct you where they want you to go. By changing your settings to enable word verification you block any automated comments like this...kind of a pain to have to type the letters in after making a comment but trust me you don't want those types of comments.
